Photolyzable Polymer Brushes: Subtractive 3D Structuring of Surfaces Using Water and Light. [PDF]

open access: yesAngew Chem Int Ed Engl
Facile structuring of polymer brushes is achieved by flipping the process from controlled growth to controlled brush photolysis. Using surface‐initiated radical ring‐opening polymerization of cyclic monomers with photocleavable cyclobutane rings, photodegradable targets are embedded into the polymer chains. The enabled continuous subtractive patterning
